CNNs improve blood flow simulation accuracy with physics-aware constraints

Researchers have developed a novel method for simulating blood flow in arteries using convolutional neural networks (CNNs) combined with domain decomposition. This approach, which incorporates a physics-aware constraint of flow rate conservation, improves prediction accuracy and convergence compared to purely data-driven CNN solvers. The universal subdomain solver (USDS) was trained on a single geometry and then applied across various stenosed artery configurations, demonstrating its potential for efficient and accurate blood flow prediction.
